找不到适合 jdcb 的驱动程序

Question

This is my first time doing sql work in Java, all I was doing was making a simple program where I open and close the connection

package exercises;

import java.sql.*;

public class JdbcEx1 {
    static Connection conn = null;
    static String dbURL = "jdbc:oracle:thin:@127.0.0.1:1521:XE";
    static String user = "labs";
    static String password = "labs";

    public JdbcEx1() {}

    public static void main (String args[]) throws SQLException {

        try{
            Class.forName("oracle.jdbc.driver.OracleDriver");
        } catch (ClassNotFoundException e){
            System.err.println(e.getMessage());
        }

        try {
            conn = DriverManager.getConnection(dbURL, user, password);
            conn.clearWarnings();
            System.out.println("Connection opened! for driver ==>Oracle 11XE");
        } catch (SQLException e) {
            System.err.println(e.getMessage());
        } finally {
            if(!conn.isClosed()) {
                conn.close();
                System.out.println("Connection Close! Oracle");
            }
        }

    }
}

Whenever I try to run it I get the following error:

oracle.jdbc.driver.OracleDriver No suitable driver found for jdbc:oracle:thin:@127.0.0.1:1521:XE

I really don't have much of a clue as to whats going on, I've tried running through it with the debugger multiple times but that just confused me even more

Answer 1

The path of the ojdbc6.jar file that you points out:

C:\\Program Files\\Java\\jre1.8.0_60\\lib\\ext ,

must be specified into the environment variable CLASSPATH .

You need to have the ojdbc6.jar in your classpath environment variable in order to have JDBC 4.0 standard support.
